Controller & Embedded System Design
From motor drivers to complex multi-sensor systems, Spried develops embedded controllers that balance performance, cost, and reliability. We handle everything from MCU selection to firmware and prototyping.
What You Get
- Custom Embedded Controllers — MCU-based systems tailored for your product requirements.
- Reliable Hardware — proper power supply design, EMC considerations, robust I/O protection.
- Motor & Actuator Control — DC, stepper, BLDC, and servo control with PID and closed-loop systems.
- Sensor Integration — digital/analog sensors, signal conditioning, calibration, data processing.
- Scalable Firmware — modular, maintainable code with OTA or bootloader updates if required.
Capabilities
- MCUs: STM32, ESP32, Atmel AVR, PIC, MSP430, CH32, Nordic nRF series
- Motor Drivers: DRV series, L298, custom H-bridges, FET-based designs
- I/O: GPIO expanders, ADC/DAC integration, PWM/Timer control
- Real-time control using FreeRTOS, Zephyr, bare-metal firmware
- Interfaces: I²C, SPI, UART, CAN, RS485, Modbus
- Industrial & IoT applications with mixed-signal inputs
- Closed-loop motor control with encoders and current sensing
- Connectivity: BLE, Wi-Fi, LoRa modules integrated into controllers
- Prototyping & debugging with custom test jigs
- Factory-ready golden images and documentation
